Snowcat runs constantly upon pairing

I built the Santa Snowcat and when I first paired it an turned it on, nothing happened. I tried again, and nothing.

So I happened to have a second set and rebuilt the cyberbrick components outside of the model and got everything to pair, got a positive message, but the PG002 servos are running without any input from the joysticks. Moving the joysticks adjust the servo speeds, but letting go doesn’t cause them to stop.

I tried the “autotrim” feature on the joysticks, which seemed to “work” but the servos still run without joystick input.

What am I doing wrong?

I’ve recently had the same error. In the end it was a cable issue in the remote control part. Try changing the correspondent cable in the remote.
